Abstract
A semi-solid metal shaping method able to precisely control shape and properties of workpiece features the combination of injection casting with die forging. It includes such steps as preparing the semi-solid slurry of metal in the injection chamber, filling it from injection chamber into moulding cavity consisting of formworks, mould sleeve and filler at low speed, and die forging. Its advantages are precise shape and high mechanical performance.
Description
Technical field:
The present invention relates to a kind of two control of semisolid forming technique of metal.
Background technology:
At present, semi-solid-state metal processing is made up of slurrying (base), heating remelting (being limited to thixotropic forming) and three parts that are shaped.Shaping totally can be divided into semi-solid rheological (or thixotroping) die casting, semi-solid rheological (or thixotroping) die forging and semisolid again and penetrate three kinds of castings.The casting die complex thin-wall housing component that easily is shaped, but the mechanical property of device is bad; The die forging quality easily guarantees, but is difficult to processed complex spare; Penetrate casting and be applicable to magnesium alloy, but it still belongs to the rheo-diecasting category, the mechanical property of device is bad equally.
Summary of the invention:
The invention provides the methods that the two controls of a kind of metal semi-solid are shaped, its objective is that the shaping processing that utilizes this method to make metal accomplishes easily to ensure the quality of products, but the processed complex device can be controlled shape and control property to product accurately in the process of a drawing.The object of the present invention is achieved like this: with the metal semi-solid slurry that makes or metal semi-solid blank in the injection chamber 3 of sealing by device for filling 6 in the bottom less than the long injection chamber 3 of 200mm is fills up to by template 4, die sleeve 2 and device for filling 6 formed product chambeies 10 from lower to upper with the low speed that is lower than 1m/s, and then from top to bottom metal semi-solid slurry or metal semi-solid blanks in the product chamber 10 are carried out die-forging forming by die forging device 1.The present invention has adopted the strong point of casting die and die forging, device for filling 6 is carrying out filling less than the bottom of the long injection chamber 3 of 200mm from lower to upper with the low speed that is lower than 1m/s when the filling raw material, in the process of filling, the stroke of filling is short, the speed of filling is low, the metal semi-solid slurry or the metal semi-solid blank density that can keep being filled with are fills up in the product chamber 10 equably, again by solidification forming under the double action of the condensation of the pressure of die forging device 1 and raw material, make the product 12 that is shaped have regular shape, size is accurate, the advantage that mechanical property is good, thereby can in a forming process, reach the purpose of two controls, promptly product 12 is controlled shape and control property accurately, especially be fit to processing aluminium, magnesium alloy and composite thereof.
Description of drawings:
Fig. 1 is the structural representation of device that the present invention adopts when original state, Fig. 2 is at the structural representation of device that the present invention adopts after product 12 is shaped, Fig. 3 is the structural representation of semi solid slurry among the present invention (base) material preparation room 11, Fig. 4 is the process chart of the preparation and the conveying of metal semi-solid slurry, Fig. 5 is the process chart of the preparation and the conveying of metal semi-solid blank, and Fig. 6 is the process chart of filling of the present invention and die forging.
The specific embodiment:
The specific embodiment one: specify present embodiment below in conjunction with Fig. 1, Fig. 2 and Fig. 3.Metal semi-solid slurry that makes in the injection chamber 3 with sealing or metal semi-solid blank are fills up to the low speed that is lower than 1m/s in template 4, die sleeve 2 and the device for filling 6 formed product chambeies 10 in the bottom less than the long injection chamber 3 of 200mm from the bottom up by device for filling 6, and then from top to bottom metal semi-solid slurry in the product chamber 10 or metal semi-solid blank are carried out die forging to being shaped by die forging device 1.Its used metal semi-solid slurry is to make and send in the injection chamber 3 by following steps: one, by proportioning device metal bath is injected slurry chamber 8; Two, sealing slurry chamber 8; Three, start magnetic stirrer 11-2 metal bath is carried out electromagnetic agitation; The temperature of regulating metal bath in the slurry chamber 8 when four, stirring makes metal bath keep semisolid, until forming metal semi-solid slurry; Five, the metal semi-solid slurry of making is sent into injection chamber 3 by conveying device 9 through check valve 7; Six, with injection chamber 3 sealings.The pulping chamber 8 outer cooling water pipe 11-3 and the heater coil 11-4 of being wound with of metal semi-solid slurry (base) material preparation room 11 are equipped with magnetic stirrer 11-2 in the outer periphery of cooling water pipe 11-3 and heater coil 11-4.
The specific embodiment two: the difference of the present embodiment and the specific embodiment one is that the raw material that is adopted is the metal semi-solid blank.It makes and sends in the injection chamber 3 via following steps: one, will be heated to the metal stock that is lower than 5 ℃ of solidus temperatures by proportioning device and place slurry chamber 8; Two, sealing slurry chamber 8; Three, metal stock is heated to semisolid, makes the crystal grain nodularization in the metal stock; Four, semi-solid metal stock is stirred; When five, stirring, the temperature of semi-solid metal stock in the slurry chamber 8 is regulated and control, made semi-solid metal stock remain on semisolid, until forming the metal semi-solid blank; Six, the metal semi-solid slurry of making is sent into injection chamber 3 by conveying device 9 through check valve 7; Seven, with injection chamber 3 sealings.
